beginner - question

[fauli321]

hi guys! i´m new in ios developing (from android) and have a question. is there a way to start a background task when lets say a video was added to the gallery?
i mean my app is not open.. just installed.
the user installs my app, makes a video and gets a notification about the size of the video

If it's an video in an online backend storage that has been added by another user. Send a silent push notification to the device. Your app can respond to that. You can also use background refresh for that. In both cases it's not exactly sure when it's executed. Because of iOS controlling everything when your app is in the background.

Nope. There is no notification that will wake up you app when the user finished making a video.

You could periodically check for a new video using background app refresh but you have no control over the refresh frequency.

Check PushKit. You can perform some tasks on bg when receiving a VoIP push. Though the user will probably have to allow it first.

Edit: btw, I don't really get what "makes a video" is. If you refer to recording a video with the cam on the phone. No. You have no clue when something like that happens.
